7.5 Changing Filter Elements
The following procedure describes how to change the filter elements for either the
particulate filter (not available on the AS-A models) semi-annually or the coalescing
filter annually.
1) Depressurize the filter assembly and shut down the oxygen generator. (See
Section 7.4, Depressurizing the Filters.)
Do not attempt to remove the filter bowls until the filter
assembly fully depressurizes as described in Section 7.4.
2) While the unit is depressurized and the power supply is disconnected,
remove the front cover of the enclosure. (See Section 7.3, Removing the Front
Cover of the Enclosure.)
3) To remove the bowl from either filter, push down the bowl latch and rotate the
bowl slight right or left while pulling down on the bowl. If filter has screws,
loosen them up.
4) When the bowl is free, disconnect the drain tubing from the bottom of the
bowl. There may be a retainer nut which has to be disconnected to remove
the filter element for the filter models with screws.
5) Wash the bowl in warm, soapy water, then rinse the bowl.
6) Gently unscrew the old filter element and discard it.
